A process and apparatus is provided for the transmission of radionuclide spectral information from a remote location. The process facilitates the use of a handheld radiation detector to detect a spectrum of radiation from a radiation source such as a cargo ship at sea. The process facilitates the downloading of information to a computer such as a PDA. The PDA is configured to allow communication with a satellite phone that transmits the stored spectrum to an evaluation center for further analysis and positive identification. Once identified, the results can be relayed to the remote location for appropriate action.
